Maxim Y.

Senior Symfony / PHP Full-Stack Developer - React Node.js Typescript

I help companies maintain, stabilize, and evolve large PHP/Symfony applications — especially systems that combine legacy code with modern architecture. Most of my work involves production systems where: the codebase is already complex (monoliths, legacy PHP, mixed stacks) new features must be delivered without breaking existing functionality performance, stability, and maintainability are critical I work across the full stack (Symfony + React) to reduce coordination overhead and deliver faster, cleaner results. Typical projects I handle: Refactoring and modernizing legacy PHP/Symfony applications Stabilizing production systems with high bug rates Designing and improving API architecture (REST / API Platform) Migrating features from legacy code into structured Symfony modules Performance optimization (database, Doctrine, caching) Full-stack feature delivery (Symfony backend + React frontend) Setting up Docker-based environments and CI/CD pipelines Core stack: PHP 8.x, Symfony (API Platform, Doctrine) React, TypeScript (Redux Toolkit) MySQL Docker, AWS (RDS, ECS/ECR, ELB) Supporting: PHPUnit, Cypress, Jest Legacy PHP systems (including older/other frameworks ) I’m a strong fit if: your system is already in production you need someone to take ownership, not just write code you’re dealing with legacy + modern stack complexity
